Application filed June 8, 1912. Serial No. 702,427.

To all whom it may concern.

Be it known that we, AsBJoRN ARNTZEN and FIND RAsMossEN, citizens ofDenmark, residing at Brooklyn, in the county of Kings, State of NewYork, have invented certain new and useful Improvements inShaft-Couplings; and'I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

Thisinvention relates to shaft couplings and particularly to a typewhich may be utilized as an emergency coupling or an ordinary powertransmission coupling.

The object of the invention resides in the provision of a coupling whichmay be utilized in an emergency without subjecting any of the parts ofthe coupling to indeterminable stresses even if shafts are not in truealinement.

. A further object of the invention resides I in the provision of acoupling in which the parts thereof may be expanded laterally so as tocompensate for gvear incident to the engagement between the cou ling andthe shaftsections connected there y.

A still further object of the invention resides in the provision of ashaft coupling which may be associated with desired shaft sections withease and facility and which may be disassociated with said sections withequal ease and facility.

With the above and other objects in view, the invention consists in thedetails of construction and in the arrangement and combination of partsto be hereinafter more fully described and appended claim.

In describing the invention in detail, reference will be had to theaccompanying drawings wherein like characters of reference denotecorresponding parts in the several views,-and in which a Figure 1 is aside elevation of a coupling constructed in accordance with theinvention, Fig. 2, a section on the line 22 of gig. 1, Fig. 3, a sectionon the line 3-3 of Referring to the drawings 10 and 11 indicaterespectively two shaft sections connected together by the coupling. Thiscupling is shown as comprising collars 12 and 13 keyed respectivelyonthe adjacent ends of the shafts and 11. These collars are provided.Ifespectively at their outer ends particularly pointed out in the rwith enlarged portions 14 and 15 and the ad acent faces of theseenlarged portions 14 and 15' are provided respectively with grooves 16and 17 extending transversely of the collars.

Disposed between the adjacent ends of the shafts 10 and 11 and betweenthe adjacent ends of the collars 12 and l3-are disks 18 and 19 whichhave a greater diameter than the enlarged portions 14 and 15 and areconnected together adjacent their periphery by breakable bolts 20. Thedisk 19 is provided with a central circular opening 21 disposed inalinement with the shafts 10 and 11 and receiving a. cylindricalproecting portion 22 formed on the disk 18 whereby a male and female fitis effected between the disks 18 and 19. This disk 18 is provided on itsouter side with a plurality of ribs 23 disposed respectively in thegrooves 16 of the collar 12, while the disk 19 is provided'on' its outerside with a plurality of ribs 24 disposed respectively in the grooves 17of the collar 13 and in this manner the collars 12 and 13 areoperatively connected to the united disks 18 and 19 for rotation withthe latter and as the collars 12 and 13 are keyed to respective shafts10 and 11 it will be apparent that the said shafts are effectivelycoupled. The shafts 10 and 11 have their adjacent ends provided withreduced portions 25 and 26 respectively which project inwardly of theouter edges of respective ribs 23 and 24 and in this manner serve tocatch and support the disks 18 and 19 in the event of ru ture of thebolts 20.

t will be noted that the disks 18 and 19 may be separated by.looseningthe bolts 20 and 20 in order to receive asuitable washer between them toeffect the permanent separation of the disks. This separation of thedisks 18 and 19 is'resorted to when wear in the machinery separates theshafts, in endwise directions so as to restore joints to their properfit. It will be further notedv that when the coupling is associated withthe shafts 10 and 11 the disks 18 and'19 are moved relatively to eachother so as to dispose the ribs- 23 and 24 at right angles to each otherand by this arrangement of the disks 18 and 19 the coupling can transmitWhat is claimed is: members, the ribs on one disk being dis- In a shaftcoupling, the combination of a posed at right angles to the ribs on theother pair of shaft'members, a pair of disks disdlSk.
